SHOCK-COMPRESSOR.

Specification of Letters Patent.

Patented Dec. 20, 1910.

Application filed November 6, 1989. Serial No. 526,515.

To all whom it may concern.

Be it known that we, CHARLES K. lVoLr and FRED MCCLAIN, both citizens of the United States, both residing near Xenia, in the county of Green and State of Ohio, have invented certain new and useful Improvements in ShocleCompressors, of which the following is a specification.

Our invention relates to devices for compressing and temporarily holding shocks of corn or other similar growth under compres sion while the permanent band or tying device is being applied.

The object of the invention is to simplify the structure as well as the means and mode of operation of such devices wiereby they will not only be cheapened in construction but will be rendered more eflicient and positive in operation, more easily operated, and unlikely to get out of repair. And, furthermore, to providea device whereby the operation of binding shocks of corn or other growths can be performed with neatness, thoroughness, and despatch, and with a minimum torsional strain.

Ti ith the above primary and other incidental objects in view as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and their mode of operation as hereinafter described and set forth in the claims.

Referring to the drawings, Figure 1 is a plan view of the assembled shock compressing device. Fig. 2 is a plan view of the tie securing member and Fig. 3 is an edge view of said member viewed from the bottom in F 2.

Like, parts are indicated by similar characters of reference tl'iroughout the several views.

In constructing the device there is employed a longitudinal member or supporting bar 1, the opposite ends of which are inclined as at Independently pivoted to the supporting bar 1 at points adjacent to the ends 2 thereof are swinging clevises 3 and t. The clevis is U-shaped, the arms 5 thereof extending on opposite sides of the supporting bar 1 and engaging the trunnions or rivet (S. The outer extremity of both clevises are somewhat elongated and formed on the arc of a circle as indicated at 7. This portion of the clevis is substantially semi-circular in cross-section as shown at 8, Fig. 3. The clevis 1 is provided with but one attaching arm 9, the opposite side of the clevis being shortened whereby the clevis 4 becomes substantially a hook. Inasmuch as the entire strain upon the hookshaped clevis it falls upon the single arm 9, said arm is preferably reinforced by the reinforcing rib 9 The curved extremities of the respective clevises comprise substantially arcuate saddles in which are engaged the extremities of the binding rope or cord. The pivotal points of the clevises 3 and 4: are so located in relation to the extremities of the supporting bar 1 that When the binding rope is in place in the arcuate saddles of the clevises, the clevises will not swing past the extremities of the supporting bar 1 but when forced to the extreme limit of their movement the noses l0 and 1 1 of the supporting bar will engage and impinge the binding rope within the clevises. Centrally located in the supporting bar 1 is a transverse opening or eye 11 for the engagement of one length of the binding rope.

Formed integral with the supporting bar 1 and extending laterally therefrom is a lug carrying a ring or handle 12 by which the nose of the supporting bar may be disengaged from the binding rope as hereinafter mentioned. The binding rope or cord comprises two lengths, the length 13 is attached to the supporting bar 1 by being passed through the central opening or eye 11 and secured by a knot or other suitable means. This length of binding rope 13 is bent upon itself to form a bight and the extremity thereof is passed through the clevis 3 and is adapted to be held against movement within the clevis by the engagement of the nose 14: of the supporting bar 1. Carried in the bight of the length 13 of the binding rope is a pulley block or sheave 15 to which is secured the second section 16 of the binding rope, the free end of which is engaged in the hook shaped clevis and impinged therein by the nose 10 of the supporting bar 1.

In using the device, the extremity of the length 16 of the binding rope is passed around the shock and its free end is engaged in the hook-shaped clevis 4. The shoek'is then initially compressed by drawing upon the free end of the length 16. The rope 16 will pass freely through the clevis 1 from the inner side but the impingement of the nose 10 upon the rope will prevent its return movement and will tend to hold the binding cord in its operated position. This initial compression of the shock by the pull ing in one direction tends to twist the shock or place it under torsional strain which tends to disarrange thestalks of corn or other growth trom their original positions, and it le'lt in this position the shock would be easily blown over and would not shed water as satistactoril as when the stalks are substantially straight. After the shock has been initially compressed the tree end of the length 13 ot the binding rope is drawn through the clevis 3 in the same manner. The nose ll; of the supporting bar cooperating with the clevis 2) tends to clamp the rope 'n its operated position. The length 13 of the binding rope passing through the pulley block 15 draws upon the opposite end of the length ill of the binding rope and completes the compression oi. the shock by tending to twist it in the opposite direction whereby the stalks disananged by the initial compression are returned to normal position. It will be noted that the pulling strand Off the tie 1 is outermost whereby it will he out of contact with the corn thereby permitting the device to be more easily operated. inasmuch as the pulling strand will not rub over the stalks ot corn and furthermore, it reduces the wear upon the binding rope. The shock when under ctmipression, through its tendency to expand presses outward in the direction of the arrows in Fig. 1. This outward pressure tends to swing the clevises 3 and 4: about their pivotal connection where by the elevises and the rope engaged there with are. pressed tightly into engagement with the inu iinging noses l0 and ll. ll'hen it is desired to release the compressing device after the permanent tie has been applied, the nose It) is pulled away from the binding rope lvti by means of the handle 12.

One of the advantages resulting from this constructimi is that there are few moving parts in which the blades of corn can become entangled, such as is the ease in a device employing a number of pulley wheels or other rotary or swinging bearings. The arcuate saddles ot' the clevises torm extended bearing surfaces whereby the rope will not be asil y worn or trayed and. they furthermore form rigid abutments against which the rope is in'ipingcd by the noses l0 and 1t oi the bar 1.

lt has been found by experience that the attachment ot the bight l3 in such a manner that the bight will lie in a plane common with the clevis as by having the opening ll extend in a p e common with the plane .he clevises, is of material advantage. it the night 1? does not pull upon the bar 1 in a plane common with the cleyises, there is a tendenc of the entire clamping device to skew or twist which interteres u ith the ease of operation.

From the above description it will be aparent that there is thus produced a device of the character described. pos essing the particular 'llatures ol. advant: belore enume add as desirable, but which obviously is susceptible of modification in its form, proportion, detail construction and arrangement of parts without departing from the principle involved, or sacrificing any oil? its advantages.

Having thus der-lcribed our invention we claim:
